Sema are a Polish company that specialise in the manufacture of expansion joints. The company is recognised for creditable and reliable service. At Sema, we ensure that our constructions operate reliably in the most hostile conditions, through careful and proper installation.
Expansion joints are flexible pipeline and channel joints for industrial installations. They are resistant to high temperature, aggressive media and internal pressure. Expansion joints ensure proper compensation of thermal and mechanical dilatations of the fumes channels, hot air pipelines and for other media.

Sema expansion joints provide many design advantages. For example, they do not contain asbestos. They demonstrate the ability to work within temperatures of up to 1,000°, and, depending on the structure, they can work with overpressure of up to three bars. Sema joints are designed and manufactured individually on the basis of specific guidelines and customer arrangements. Additionally, Sema joints are provided by the orderer, with the ability to compensate dilatations of different directions, compensate and dampen vibrations of connected channels, and reduce noise. They are easy to mount, allowing quick repair of the compensator coat.
